I'm 19 and just had a baby my teeth have turned yellowy is there any teeth Whitening that works?

I really don't know where to start. Peole look at my mouth when I speak it puts me off . My teeth are not that bad but not as White anymore

you could go to your dentist and get them bleached but that tends to be a little bit costly. but i have tried the Crest white strips and i saw a difference pretty fast. but those are also a bit expensive. either way you look at it. to get your teeth white again is going to cost you a pretty penny lol. good luck i hope this helps :)
